The AC resistance of carbon nanotube fiber (CNTF) yarn wires has rarely been studied at megahertz (MHz) frequencies. However, there is a growing demand for magnetic devices, including transformers and inductors, implemented in high-frequency power-converter circuits. Recently, a study on the skin ef...
